Definitions

  • the invention relates to an automatic lubricant metering device for the lubrication of a rotating shaft, with a piston / cylinder system, the piston of which is acted upon by a pressure medium, which is preferably a compression spring lying in the housing above the piston with a very flat characteristic, the lubricant supply is arranged below the piston in the cylinder and is located in a closed, compressible bellows, - And the piston is in operative connection with an abradable material, the material being in abutment-promoting position of the shaft.
  • a pressure medium which is preferably a compression spring lying in the housing above the piston with a very flat characteristic
  • Such a device is known from US-A-3206261. It is a device which is not concerned with actual dosing, which is understood to mean constant conveyance. Rather, the spring-loaded piston only acts on the lubricant bellows when the abradable material in the form of a pin is completely rubbed off. A large amount of grease is fed into the roller bearing in one go.
  • the device is designed in a ring shape and is in the immediate vicinity of the lubrication Bearing arranged within the housing. Due to this internal machine installation, the conveyor device is subject to regular checks with regard to function control and lubricant level. In addition, this configuration makes subsequent installation in existing machines impossible. It is particularly unsuitable in systems in which new lubricant has to be added to the bearing point during operation.
  • the invention is therefore based on the object of providing a simple, maintenance-friendly and constantly effective lubricant delivery in operation.
  • the housing of the device is arranged on a stationary machine part surrounding the shaft to be lubricated, preferably in the vicinity of a free shaft end, - that the bellows is provided with a feed line to the lubrication point, - And that the supply line to the lubrication point in the shaft area takes place via a pipe, which preferably lies in a contactless manner in a central bore of the shaft, the outlet of which opens into a radial bore connected to the lubrication point.
  • Such a lubricant dosing device can be arranged in any angular position on the machine part. Furthermore, there is no need for any pipe screw connections and seals on the shaft side when introducing the supply line.
  • the shaft bore is provided with a circumferential collecting groove for the lubricant in the plane of the mouth of the tube or the radial bore, this has the advantage that even when the shaft is at a standstill, the temperature-dependent dripping of lubricant out of the Supply pipe does not lead to leakage from the central shaft bore.
  • the pressure medium is a compression spring with a very flat characteristic lying above the piston in the housing, you have a simple tool in hand, with otherwise fixed parameters using the mere selection of springs, the amount of lubricant to be pumped per Determine unit of time.
  • the bellows be divided into several chambers with separate contents, the chambers each extending over the entire cylinder height.
  • the chambers can be arranged next to one another over the circumference, or they can be formed as concentrically nested ring chambers.
  • the abradable material is a pin made of graphite, for example, which is connected to the underside of the piston and penetrates the stationary machine part via a bore and is pressed against the shaft surface.
  • the piston / pin functional unit thus created can also be created as an interchangeable commercial unit.
  • the abrasion-promoting point of the shaft is corded or cross-bordered and preferably extends over the entire circumference of the shaft, this targeted roughness can be used as a fixed value for the coordination with the abradable pin and the compression spring.
  • FIG. 1 parts that are not essential to the invention, such as, for example, the structure and the mode of operation of the machine belonging to the bearing, are omitted.
  • the shaft 1 is a bone shaft and that the cam 20 is guided in a plain bearing.
  • the machine part provided with the bearing metal 22 can be a disk following the cam movement.
  • the annular gap 21 between the cam and the bearing metal thus forms the actual lubrication point 2.
  • Grease lubrication is used as a basis. Lateral bearing seals that may be required are not shown.
  • the free, cantilever shaft end is surrounded by a fixed machine part 3, for example the outer housing of the machine. This is at the extreme end of this machine part 3 Flanged housing 4 of the dosing device by means of a screw connection indicated by dashed lines.
  • the basic shape of this housing can be any.
  • a piston 5 Connected to the piston is a cylindrical pin 6, which according to the invention consists of a low-wear, ie abradable material. Depending on the desired feed rate, this can be graphite, a graphite-containing substance or some other suitable material.
  • the length of the pin is such that in its uppermost position in cylinder 7 it penetrates it on the ground and presses against shaft 1 through a bore 8 in stationary machine part 3.
  • the counter surface on the shaft is mechanically roughened in the form of a cross border 10.
  • the border extends over the entire circumference of the shaft and is designed so that the abradable material of the pin 6 does not clog the valleys cut into the shaft surface.
  • the pressure medium 9 required for the abrasion in the present case is a metallic pressure spring with a very flat characteristic. It is located in the housing 4 between the top of the piston and the cover 24. Of course, any other pressure medium is suitable which is capable of pushing the piston 5 through the cylinder 7 with an approximately constant force.
  • the pressure medium 9 does not only have to overcome the pressing force of the pin 6, but particularly has to perform the function of a lubricant conveyor.
  • the lubricant here grease, is located in the cylinder 7 below the piston 5. It is contained in a closed bellows 11 which is arranged around the pin 6 and thus fills the cylinder. The bellows is designed so that it can be compressed by the pressurized piston 5.
  • this feed line consists of a bent tube 13.
  • One of the tube ends is inserted into the bellows 11 through a housing opening, or a mouthpiece of the bellows can be placed over the pipe end.
  • the other end of the pipe penetrates deep into the shaft 1 without contact.
  • this shaft 1 is provided with a correspondingly dimensioned central bore 14, which extends from the shaft end to the level of the lubrication point 2.
  • the pipe end is chamfered in such a way that it releases the lubricant directly into a radial bore 16, which opens directly into the lubrication gap.
  • the lubricant metering device in a system, the interior of which - as indicated by dash-dotted lines - is closed off from the outside. It can be a compressor, which means that the space 26 between the moving parts 1, 2 and the stationary machine part 3 is under pressure.
  • the fixed part 3 that is to say the machine housing, is provided with a front closure 3 ⁇ in the area of the shaft end to avoid loss of working fluid.
  • the cylinder 7 and thus the bellows 11 are subjected to the same pressure as prevails in the space 26 and thus also in the shaft bore 14a.
  • the feed line 12 is led out of the metering device through the bottom of the housing 4 and passed into the shaft area via a correspondingly arranged through hole 27 in the machine part 4.
  • the through hole 27 and the bottom opening are dimensioned such that the feed line 12 penetrates the two in a non-sealing manner.
  • the cover 24 is sealed against the housing 4 and the housing base against the machine part 3. In the present case, this is done by simply attaching runner seals 28, respectively. 29 shown.
  • a pressure equalization bore 31 connects the closed interior around the shaft end with that around the moving machine part 23.
  • the lubrication gap 2a of this support bearing is supplied via a radial bore 16a in the shaft 1.
  • the shaft bore is provided with a catch groove 32a in the plane of the radial bore 16a. Since independent lubrication is provided, the radial bore 16a is fed to a separate feed line 12a via the tube 13a.
  • the central shaft bore 14a is dimensioned correspondingly larger to accommodate the two tubes 13 and 13a.
  • the supply line 12a is connected to the bellows 11 via through holes 27a in the machine part 3 and in the housing base.
  • each feed line is connected to its own bellows section.
  • the vertically divided chambers 25, 25a can also have different cross sections, in deviation from the shape shown.
  • appropriate amounts of lubricant are then conveyed into the feed lines to these cross sections.
  • FIG. 4 An arrangement is shown in FIG. 4 for which the supply line guide described in FIG. 2 is particularly suitable.
  • the separate chambers 25b, 25c are nested here and form cylindrical annular chambers. It is easy to see that here too, different quantities can be conveyed per lifting unit simply by assigning appropriate ring cross sections. A lateral lead-out of the leads would be cumbersome for the inner chamber 25c.
  • FIGS. 3 and 4 Another advantage of the arrangements shown in FIGS. 3 and 4 can be seen in the fact that with a single metering device it is possible to deliver different types of lubricant according to the needs of the bearing points.
  • the invention is not limited to the exemplary embodiments shown and described.
  • the choice of pressure medium, of the abradable material, of the roughness of the shaft at the point of attack and even of the lubricant is hardly restricted.
  • other additional devices such as an external display of the respective piston position, a wear indicator and the like, can make the handling of the device even easier.
